Their son, Tong Yongjie, was among the four survivors, but Tong Fuliang still broke down in tears in the hospital ward.
"I want to take him with me to Zhejiang. Though life might be bitter out there, it helps me feel calm with the family around," Tong Fuliang told Xinhua.
Tong Boliang, 59, felt a bit relieved because his grandson boarded a different van that day. (The two Tongs are not related.)
"If he was a bit late and took the second van, I might have missed him forever," said Tong Boliang.
He said his grandson is already in elementary school but, like many others who live in the area, the family pays 200 yuan (32 U.S. dollars) a semester to use the Chunlei Kindergarten van to commute to school.
